Improved apparatus for the manufacture of illuminating-gas



UNITED STATES PATENT EFICE.

JOHN A. BASSETT, OF SALEM, MASSACHUSETTS.

IMPROVED APPARATUS FOR THE MANUFACTURE OF ILLUMINATING-GAS.

Specification forming part of Letters Patent No. 83,239, dated October20, 1868.

To all whom it may concern.-

Be it known that I, JOHN A. BAssETT, of Salem, in the county of Essexand State of Massachusetts, have invented a new and useful Improvementin the Manufacture of Illuminating Gas from Volatile Hydrocarbons; and Ido hereby declare the following to be a full, clear, and exactdescription of the same, reference being had to the drawing annexed,forming a part of this specification.

This invention relates to that class of gasmakin g machines in which airis impregnated with the vapor of a liquid hydrocarbon, the object beingto cause the air to enter into immediate and prolonged contact with thevapor of the liquid. In this class of .machines the air is compelled topass under the surface of a floating disk in direct contact with thehydrocarbon, and, escaping at the periphery of the disk, becomesimpregnated with it.

The nature of this invention consists in forming this disk of wood witha number of semi-cylindrical channels upon the under side of it,radiating from the center, so that the air is divided into a number ofstreams in its passage under the disk, before escaping at the outside,so that it escapes uniformly all around the circumference.

The advantage of using wood for this pur- A pose is evident to those whohave had experience with this class of machines. A metal disk isdifficult and expensive to make, and the level above the hydrocarbon istroublesome to adjust.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an apparatus for carbureting air, the

disk O, made of wood, floating upon the surface of the hydrocarbonliquid and partially immersed therein.

2. The disk C, having radiating channels formed upon the under surface,for the purpose substantially as described.
